new and useful'lmprovements in Trailers,

of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to trailers for auto mobiles, and my lllVeIltlOIl' aims to provide a single truck trailer witha rest. member orsupport that may be raised orrlowered, either to support one end of the trailer when not attached to a vehicle or to assumean inactive position when the trailer is attached to vehicle. The truck trailer is also provided with a brakemechanism that may be actuated by the restflmember', actuated fromthe vehicle to which th'etrailer is connected, or actuated independent of thevehicle and, the rest memberl In pulling a loaded trailer, it is necessary that the brakes of-the trailer can be controlled from the vehicle towhich the trailer is attached, and it is equally necessary that the brakes of the-trailer may be set or applied, when thetrailer' is not attachedto a vehicle,: so that it cannot be accidentally.

moved. Furthermore-"it is necessary that some; means he provided whereby the applied brakes of the trailer may be released so that [the trailer mayfbe moved about,

without being attached to a tractor,-truck or other vehicle. Allv o'f this isaccomplished be here nafter described andthen claimeda Reference will now be; toj'the dr ings, wherein- I of a trailer accordancewith my inven- Figur'e 1 is a longitildinal "sectional I view tion;

In the drawing, the reference, numeral ,1 i denotes a: -'port io'nof. the-"conventional for'mlf of trailer "frame which has the firearm 'fhead'orsleeye 23 is normally held inengagement with the pin 26 by afco'iled "compres-f' sion spring 27, encircling thestud 24, bee tween the'head 23 andthe'side-of the frame .8, The; crank or lever 22"'is thereforenorthereof-supportedby springs- 2 on an axle 3,

said axle, having the ends'the-reof provided with'wheels 4-and brakes5; The axle and its wheels constitute a' single rear truck and B. WINN, a

shaft 7 and mounted on said rock shaftis a' rest or supporting member, comprising a substantially V-shaped frame 8 which has the lower end thereof provided with a fifth wheel 9 or a universal joint supporting an axle 10, and on -the ends of the axle are wheels 11. The rest inember, as shown, is in an inactive position,-off of the ground and is maintained in such position while the trailer is attached to a vehicle. Any suitable means may be employed foriholding the rest member in an inactive position and when said rest member is swung downwardly the wheels 11 are positioned above the ground so ,as to cooperate with the single truck in supporting the trailer immediately after the vehicle lowers and releases the forward end.

of the trailer,

The trailer truck, has hangers 12,- and-in said hangers ,isa rock shaft 18. vThe en-ds-of the rock shaft '13-'are provided withcrankslei connectedby links late the brakes5, so that by rocking the shaft 13 t-h el r akes may-be released orapplied.

v- The :rockshaft 13,:has-a crank 16 and connected to said crank is a reach rod 17 that extendsforwardly and maybe actuated from the tractor, truck -or vehicle, to which the trailer is attached. A The rock shaft 13 hasan additional crank frame 1, adjacent. the single;

1'8- and-slidable' in the lower "end of said of provided with an adjustable head 20,

preferably in the form of a nut, adapted-toengage the crank 18 andnactnate the rock shaft 13 when the rod-19 is-shi'fted. The forward endvof. the rod is pivotally con-R ,nected, as at 21 to a long crank or'lever' 22 that has a slotted-headpr sleeve '23 normally fixed on a stud;-.24:, carried by the sideofthe frame 8; The header sleeve 23, is slot- .tegl, as-at; 25, to; receive the'endsof a transa ers'e rpin 26 ,-carried.by the stud 24, and the 105 mally fixed relative to crank is a rod 19 having the rearend' thereber 33 can be therewith, but by shifting the crank or lever 22toward the frame 8, the head or sleeve 23 is moved out of engagement with the pin 26 and said crank or lever is loose relative to the stud 24.

It is now apparent that the brakes 5 of the trailer may be released or applied from the vehicle to which the trailer is attached; that when the rest member is lowered the brakes 5 maybe applied through the medium of the cranks 22 and 18, and rod 19, so that the trailer will not accidentally move particularly if left standing on a grade; and, that by releasing or unlocking the crank 22, thetrailer may be manually moved about from place to place with the rest member cooperating with the rear truck of the trailer.

In Fig. 4 there is showna universal joint that may be used as a fifth wheel, said joint comprising a member 28 fixed on an axle 29 and provided with a king bolt 30 for a swiveled block 31 having 'trunnions or gudgeons 82. The lower end of a rest memplaced on the trunnions 32, so that the axle 29 will have a universal movement relative to the trailer.

' It isthought that the operation and utility of the trailer will be apparent without further description, and while in the drawing there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

That I claim is 1. In combination, a trailer'of the single truck type, a movable rest member carried by the forward end of the trailer and adapted to move to and from a position to form a support for such end when the trailer is detached, and brake mechanism for the truck, said mechanism having connection with said rest member operative to apply the brakes when said member is placed in rest position, said mechanism also including means for applying such brakes at will.while the rest member is out of such position.

2. In combination, a trailer of the single truck type, a movable rest member carried by the forward end of the trailer and adapted to move to and from a position to form a support for such end when the trailer is detached,'and brake mechanism for the truck, Said mechanism, including a rock shaft operatively connected to thebrakes to control the operations of thelatter, connections between the shaft and said rest member to apply the brakes when the member is in rest position, and independent connections lead ing to such shaft and operable at will for setting the brakes when the rest member is out of such position. I

3. In combination, a trailer of the single truck type, a movable rest member carried by the forward end of the trailer and adapted to move to and from a position to form a support for such endwhen the trailer is detached, and brake mechanism for the truck, said mechanism having a connection with said rest member normally operative to apply the brakes when said member is in rest posi tion, said mechanism including means oper-- the member is in such position.

4. In combination, a trailer of the single truck type, a movable rest member carried by the forward end of the trailer and adapted to move to and-from a position to form a support for such end when the trailer is detached, and brake mechanism for the truck, said mechanism including a crank ative to temporarily release the brakes when normally having a fixed relation to and movable with the rest member and adapted to normally apply the brakes when said member is moved into rest position, .and

means for temporarily releasing the fixed re lation of crank and member to permit relative movement therebetween.

5. The combination of a trailer having a single truck, and a pivoted rest member for the forward end of said trailer, said. rest member comprising a frame, a fifth wheel at the lower end thereof, and an axle and wheels supported by said fifth wheel, said axle and wheels forming a unit in which the wheels are spaced a distance greater than the width of the trailer frame.

6. The combination of a trailer having a single truck, a pivoted rest member at the forward end of said trailer, an axle having universal moy ement at the lower end of said rest member, and revoluble-wheels on said axle, said axle and wheels'forming a unit in which the wheels are spaced a distance greater than the width of the trailer frame.

In testimony whereof'I aflix my signature in presence of two witnesses.
